DeltaWorld: Physically Consistent Interactive World Simulators via Action-Conditioned Latent Increment Learning
DeltaWorld is a preprint describing an interactive world simulator for robot manipulation that predicts action-conditioned latent increments instead of full future latent states. On a self-collected cross-robot dataset it reduces FVD by 46.6% and LPIPS by 31.1% relative to the IWS baseline, and on the IWS benchmark it improves FID from 44.16 to 36.04. This matters because more stable long-horizon action-conditioned video prediction could reduce real-robot rollouts for policy training and evaluation.
